It's a short recording of a small string orchestra tuning before rehearsal. You can hear the strings tuning and someone humming along. Recorded with a zoom h2.
I think this sounds a bit like a jazz age theme reflecting a journey by steam ship. It was bolted together from little loopable sections (also uploaded separately here) which were all created using edirol orchestral samples and the magic of arpeggiating programs. Feel free to use this for anything you like without crediting me, or assemble your own tune out of the individual sections.
Choro "Sofres porque queres", composed by Pixinguinha and played by ensemble "Choro Pixinguinha" (Pixinguinha in the flute and Tute in the 7-string guitar). Recorded in 1919 by Odeon.
